Final answer:
The Treaty of Paris of 1783 ignored the American Indians, which is true, and it is false that both the Americans and the British gave up claims to the Mississippi River as only the British recognized American claims to the territory.
Step-by-step explanation:
The Treaty of Paris of 1783 was indeed a significant agreement that shaped the boundaries and future relations between the United States and Great Britain post-American Revolution. One important aspect of the treaty is that it, for all practical purposes, ignored the American Indians. This is true as the treaty did not take into account the numerous Indian tribes that had participated in the war and were affected by its outcome. The treaty also established new boundaries, notably granting the United States land up to the Mississippi River but not relinquishing British claims. Therefore, it is false that both the Americans and the British gave up claims to the Mississippi for the sake of peace; only the British acknowledged American claims while retaining their own interests north of the agreed boundary.
